The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimetric analysis/differential thermal analysis TGA/DTA, and dynamic mechanical thermal analysis (DMTA). The obtained results reveal PI (4), which was obtained from BAMO and 4,4'-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) exhibited the best thermal and mechanical properties.
